TYPE-WRITER ATTACHMENT.

To all whom, it may concern:

Be it known that I, ENGLAND J. BARKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Type-Writer Attachments, of which the following is a full, clear, and exact description.

My invention relates to means for supplying continuous strips of paper to the revoluble I platen of .the reciprocal carriage of a type-writing machine from one or more rolls of paper. This has been done before, but so far as my experience extends impractically, both because of the difliculty in feeding the said aper to the platen, and because the use of evicesof this kind makes the machine harder to operate and retards work on the same.

The object of my invention is to provide means for carrying one or more rolls of paper that are independent of the typewriting machine, and comprise a suspended rack which reciprocates with the carriage of said machine without in the least interfering with the freedom of movement of the latter, and always feeds the paper to the platen in a straight course.

Another object of my invention is to provide a stationary cuttingedge for tearing off the aper after it has been written upon, which is independent of the carriage and is supported by the means for carrying the paper.

Still another object of my invention is to carry the manifolding ribbon-reels at each end of the carriage in such manner and by such means that the course of said ribbon from one reel to the other will always be in the same longitudinal direction, and yet another object is to intermittently rotate said reels at the end of each throw of the carriage by stationary means which may be supported either by the supporting frame of the type-writer, or by the frame-work supporting the racks that carry the rolls of paper. This I accomplish by the means hereinafter fully described, and as particularly pointed out in theclaims.

In the drawings: Figure 1 is a longitudinal vertical section of my improvements showing the type-writing machine in connection with which it is designed to be used in dotted lines. Fig. 2 is a front elevation of the same detached from said machine. Fig. 3 is a plan view thereof showing a dia- Speclflcatlon of Letters Patent.

grammatical view of the machine in dotted Ines. Fig. 4 is a detail view showing a plan view of t e lower cross-member of the rack supporting the paper-rolls to the carrier and the forwardly projecting arm that extends and is attached to the typewriting machine and fragments of the latter. Fig. 5 is a detail view showing a side elevation of the broken away upper portion of the supportmg posts of the supporting frame-work of said racks, and the folded back members of the train that supports the truck that carries the cutting-edge. Fig. 6 is a detail view showing a cross-section of said cutting-edge, and the platen and shield of the type-writing machine in diagrammatical relation thereto. Fig. 7 is a detail view showing, in perspective, a fragment of said cutting-edge and a fragment of the end frame of the carriage of the typewriting machine.

Referring to the drawings, A, represents a suitable platform, which is, preferably, rectangular, as shown in Fig. 3 thereof, and has a typewriting machine, B, say of the well-known Oliver type, mounted thereon, which is shown in dotted lines in Figs. 1 and 3 of said drawings. The typewriting machine (hereinafter referred to as the typewriter) consists of the usual reciprocal carriage, X. a rotatable cylindrical platen, Y, journaled in the ends thereof, key-board, and so forth, and is, preferably, placed about. the center of length of said platform with its front edge even with the front edge of the same. A post arises from each of the rear corners of said platform, and I prefer them to constitute the corresponding upright members a, a, of a U-shaped frame at whose horizontal portion is screwed or otherwise secured to the platform parallel to and next its rear longitudinal edge. These posts a, a, rise about twice the height of the typewriter and their upper ends are connected by a round bar or tram B. I strengthen these posts by means of inclined struts or braces I), b, that extend from about their centers of height to the end edges of the platform. The upper ends of said posts have screws tapped into their outer surfaces thereof whose barrels provide pivots for corresponding arms C, C, which latter extend horizontally forward and are retained in this position by means of stop-pins 0 driven into the posts back of said pivotal screws and enter vertical recesses in the rear extension of arms C, C, when the latter are in their ,ward and are connected bya horizontal bar or rod E, and at about the angle of the bends.

thereof brackets consisting of short flat strips of metal d, d, that extend in an inclin'ed direction tOWt llththe rear of the platform such a distance that they terminate in a horizontal plane slightly higher than thelower ends of said hangers. These brackets are connected by a rod or bar e, and this rod 6 and connecting rod E constitute a' track for a truck that supports the mani-;

folding ribbon-reels, the cutting-edge upon which the paper is torn OE and conjunctive structure, substantially as will hereinafter projecting arm N, secured to the center of be more fully explained.

The paper-rolls from which the continuous strip of paper is fed to the platen of the typewriter are journaled in the verticalmembers of a rectangular frame, F, which, preferably, consists of an inverted U-shaped fiat bar metal member whose lower ends are connected by horizontal parallel rails.

The upper horizontal part of the U-shaped member of the frame is suspended bymeans of U-shaped pulley blocks f, f, between whose ends concave wheels are j ournaled that rest and are adapted to travel back and forth upon tram B. The vertical members of said frame have their fiat broad sides inv a Vertical longitudinal plane, and the rolls of paper G, are journaled in suitable bearing devices secured to these vertical portions of frame F. It makes no difference what these bearing devices are so long as they satisfactorily accomplish'the journaling of. said rolls of paper, but, in view of the factthat the said rolls best adapted for use in connection with these improvements, have tubular paste-board cores, I prefer to secure to the vertical member at one side of the:

rack centering bosses g, g, of a'diameter corresponding to the inner circumference of the core of the paper-roll, to adapt them to enter the adjacent end of the core ashort distance,

and to provide said centering bosses with circumferential flanges, preferably, of a greater diameter than that of the rolls. These bosses are mounted upon the ends of short spindles h, that extend through and have suitable bearings in one or more bearing-lugs 1', se-

bosses j are mounted, extend through bearings 3" made integral with and projecting rearwardly from the offset upper end of a bearing frame J. These bearing-frames J have their lower ends pivoted to the adjacent vertical portions of the frame F. Just below the bearing-lugs y" bearing-frames J are widened and are each provided With'a segmental slot 70, through" which screws are passed that are tapped into the frame F until the heads of said screws bear against the bearing-frame. Thumb nuts are then screwed onto their forward screw-threaded portions until said nuts bear against the frame and clamp the bearing-frame J in such position that the. bosses will journal the paper rolls and at the same time bear end- I wise against the same to provide such resistance to the unwinding of-the paper in transit to the platen that said paper will always be taut.

The lower end'of'the suspended frame F1 has the rear end of aho-rizontal forwardly length thereof in any suitable manner. The forward end of this 'armis, preferably, bi-

furcated so as to engage one of the blocks in which the rear-wheels of the carriage of the typewriter are j ournaled. It doesnt make any particular difference how the forward end of this arm' is attached tothe carriage, but this must be done in some satisfactory manner in order that the movements of the carriage may be imparted to the suspended frame and moved simultaneously therewith back and forth on tram B.

As hereinbefore stated, rods E and 6, constitute a track for the truck that supports the manifold ribbon-reels, and this truck is free to move back and forth inzthe same direction as the carriage of the typewriter,

independently thereof but simultaneously therewith. This truck comprises a longitudinal reach, 2, and consists of an angleiron bar, the horizontal portion of which extends under rod E, between the end frames of the carriage of the typewriter and its 0 torn off, if desired, when pulled upward against the same. The vertical portion of this angle-iron reach extends in front of connecting-rod E, audits ends extend beyond the ends of the carriage and are bent away from said connecting-rod and then extend 12o longitudinally in a downwardly inclined direction a distance approximately corresponding to two-thirds of the length of the carriage of the machine. The ends of these downwardly inclined extensions 4, are bent back to form a crook 5, and in the parallel portions of the crook, at the right-hand end of the typewriter, a transverse horizontal spindle 6, is journaled which'is intermittently rotated through the medium of a 13o ratchet-wheel 7, securely mounted thereon between the same parallel portions of the crook by means of a pawl, 9, pivotally connected to an arm 10, which latter is loosely mounted on said spindle alongside'of said ratchet. Arm 10, depends downward from said spindle and it has an oscillatory movement that is limited by stop-pins 12, projecting from the rear parallel portion of the crook, and the lower end of this arm is provided with a spring-actuated finger 13, that is pivotally attached thereto, and extends below the lower extremity of the arm, and is permitted to swing in a direction away from the adjacent end of the carriage, but cannot move in the opposite direction beyond the longitudinal plane of said arm.

When the carriage of the typewriter is approaching the limit of its movement, say, to the right, finger 13, will engage the laterally bent end of a stationary arm 15, and the pendant arm 10 will move in a direction opposite the movement of the carriage, and cause the pawl 9 to engage said ratchet-wheel and rotate said spindle. The spindle 6, extends forward from its bearings, and has a manifold ribbon-reel 16 securely mounted thereon and rotatable therewith, and in front of this ribbon-reel, the spindle is screw-threaded and has a. coilspring, 17, surrounding the same, which is made to bear up against the reel by a thumbnut, 18, screwed onto the forward end of the spindle.

The construction of the manifold ribbonreel and its conjunctive mechanism at the left-hand end of the carriage is the same as that at the right-hand end, excepting that the depending arm 19 is pivoted to the downwardly inclined extension, 20, of the reach, nearer the adjacent end of the carriage, and the spring-actuated pawl 23, pivoted thereto, engages the ratchet-wheel, 21, on the spindle of the ribbon-reel 21 at a point substantially opposite the point where the pawl 9 engages ratchet 7. The lower end of this last mentioned depending arm is also provided with a spring-returnable finger 3 which is pivoted thereto and extends beyond the lower extremity thereof. This finger rides over the end of a stationary stop 22, when the carriage is moved from right to left, but is engaged by said stop when the carriage is moved in the opposite direction and causes the arm to which it is attached to move on its pivots so as to impart an intermittent movement to the left hand manifold ribbon-reel. The pawls 9 and are each adapted to Wind the manifold ribbons upon their respective spools 16 and 21* according to the direction of travel of said ribbons. This direction of travel is determined by releasing one of the pawls 9 or 23 so that it will not engage its ratchet, thus throwing its spool out of operation and causing the ribbons to wind upon the opposite spool.

The ribbon from one reel passes longitudinally upward over an idle-sheave 32, ournaled in a stud 33, projecting forward from the extension of the reach, and continues in a horizontal plane longitudinally on the top of the platen and beyond the opposite end thereof, and then to and over an idlesheavc 34, to the opposite reel. The course of the ribbon is always in the same longitudinal plane, and there are no guiding elements that change its course upon which the rib bon could catch and hold to prevent the intermittent motion of said ribbon reels.

The reach 2 and the elements it carries are supported in the positions hereinbefore described by'means of a truck comprising a pair of concaved wheels 24, adjacent each end of the reach just beyond the ends of the carriage. One of each pair of these wheels rests upon rod E, and the other or rearmost wheel of each pair bears up against the underside of rod 6. The forward end of the axles 25 of these wheels extend slightly beyond the vertical plane of rod E, and hangers 26, 26, are mounted on these forward ends and have their lower ends suitably attached to the extended portions of the reach. Angular brackets 27, 27, are screwed or otherwise attached to the rear extremities of axles 25, and the vertical branches of said brackets are connected by a horizontal rod 28 upon which blocks 29, 29 are mounted and adjustable longitudinally, and maintained in any position to which they may be adjusted by set-screws 30. These blocks constitute gages for directing the paper from the paper-rolls to the platen, and in addition have studs projecting from their forward sides upon which concaved rollers 31, 31, are journaled, that bear and travel upon rod 6.

By loosening blocks 29, the truck and attached reach and the devices supported thereby can be easily removed from the suspended track composed of rods E and e, and said suspended track can be raised up and out of the way by folding back the arm C, and the hangers D, substantially as shown in Fig. 5, of the drawings.
